New Delhi: The Narendra Modi government has been suppressing evidence of corruption against former Delhi Chief Minister Shiela Dikshit under a "deal" with the Congress, city Water Minister Kapil Mishra said on Monday.

Mishra is set to be questioned on Monday by the Anti-Corruption Branch (ACB) in the water tanker scam.

"Modi ji we have given you all the evidence against Sheila Dikshit. Then why are you saving her? What is your deal with corrupt Congress," he asked in one of his tweets.

"You control the ACB and CBI (the Central Bureau of Investigation). If you find any evidence of corruption against us, put us in jail. But why are you suppressing the evidence against Dikshit that we gave you," Mishra said in another tweet.

In yet another tweet he said: "Modiji you have used all your machinery against us. Everyone has been ordered to go after Arvind Kejriwal. I am just a scapegoat. But God is with us."

Mishra, along with his supporters, will march to the ACB office to appear for questioning.

The Aam Aadmi Party (AAP) government in June 2015 set up a five-member fact-finding committee to probe alleged irregularities in hiring 385 stainless steel water tankers by the Delhi Jal Board in 2012 during the Congress government led by Dikshit.

The committee's report, submitted to Chief Minister Arvind Kejriwal in August 2015, highlighted alleged corruption of Rs 400 crore in the process of awarding tenders for hiring water tankers.

It recommended that a first information report (FIR) be registered against Dikshit and an investigation be conducted by the CBI and the ACB.

On June 20, the ACB registered an FIR not only against Dikshit but also against Kejriwal in connection with the water tanker scam.

The FIR against Kejriwal was registered on the complaint of Bharatiya Janata Party (BJP) legislator Vijender Gupta "for causing delay in the probe and not cancelling the contract for water tankers".
